Scientific Name:

Bathyraja aguja

Species Authority:

(Kendall & Radcliffe, 1912)

Common Name/s:

English

–

Aguja Skate

Taxonomic Notes:

The paratype of Bathyraja aguja designated by Kendall and Radcliffe (1912) was found to be distinct and was later described as Bathyraja peruana McEachran & Miyake, 1984. Thus, Bathyraja aguja is known only from the holotype.

Assessment Information [top]

Red List Category & Criteria:	Data Deficient ver 3.1
Year Published:	2006
Assessor/s:	Ishihara, H. & Huveneers, C.
Reviewer/s:	Haywood, M. & Kyne, P.M. (Shark Red List Authority)
Contributor/s:
Justification: A very poorly known deepwater skate from the Southeast Pacific. Known only from the holotype collected in 1904 at a depth of 980 m off Point Aguja, Peru. Holotype was a 480 mm TL immature female, but there is no available information on the species? biology. Area of occurrence presently thought to be outside commercial fishing operations. However, as deepwater fisheries worldwide continue to expand, and given the species? potential narrow distribution, any fisheries which operate in the species? area of occurrence in the future will need to be monitored carefully to ensure that the current population is not detrimentally affected. At present, insufficient information is available to assess this species beyond Data Deficient.

Geographic Range [top]

Range Description:	Known only from the type locality off Peru in the Southeast Pacific. Further surveys are required to better define the species? range.

Habitat and Ecology [top]

Habitat and Ecology:	A very poorly known skate, known only from a single specimen collected at a depth of 980 m, a 480 mm TL immature female. Oviparous like other skates, but the biology of this species is virtually unknown.
Systems:	Marine

Threats [top]

Major Threat(s):	Known specimen was taken in an area presently thought to be outside commercial fishing operations. However, as deepwater fisheries worldwide continue to expand, and given the species? potential narrow distribution, any fisheries which operate in the species? area of occurrence in the future will need to be monitored carefully to ensure that the current population is not detrimentally affected.
